Tape Mode using the Auto Rewind Option of playback

The following fig. showed a typical playback circuit for auto rewind mode. We add a

slide-switch between /REC pin and VSS, and add 2 tact-switches /M0_Tg, /M2_CE pin and

VSS. When the slide-switch fixed in float side and press /M0_Tg pin, chip will start message

playback.

Note: After reset, /REC and /M0_Tg, /M2_/CE and /M7_Option pin will be pull-up to VDD by

internal resistor.

On power-up, beep twice and the device will be ready to playback from the first address of

memory array. Send a falling edge to the /M0_Tg pin to play the present message. During

the playback, send a falling edge to/M0_Tg pin then it will stop playing & beep once. After

stop playing, sending a falling edge to /M0_Tg pin again, it will start to play the next message.

After playing the last message, send a falling edge to /M0_Tg pin, and it will beep once to

remind you & auto-rewind to the first message. If /M0_Tg pin is kept in low potential

continually, the messages will be played to the last one & beep twice repeatedly. When

/M0_Tg pin is back to high potential, the beep voices stop and the message will be

auto-rewind to the first message.
